Dear MacPorts-Users, I'm a new MacPorts user. For my first installation, I installed gFTP because I wanted to use FTP with an IBackup.com account. I have an iBook G4 running Mac OS X 10.4.8 (PPC), MacPorts 1.320, X11 1.1.1 and Xcode 2.4. I successfully installed MacPorts and gFTP. I successfully used gFTP in the unencrypted FTP mode and both uploaded and downloaded a file from IBackup.com. I also successfully uploaded and downloaded a file using a trial copy of Panic Transmit 3 using FTP with SSL, so I'm pretty sure I got the IBackup.com settings right. I would like to use gFTP in the SSL mode. When I tried it, I got an error message. Here is the activity log: Looking up secure3.ibackup.com Trying secure3.ibackup.com:27 Connected to secure3.ibackup.com:27 220-FTP with SSL Encryption Enabled 220 IBackup FTP Server Ready. AUTH TLS 234 AUTH Command OK. Initializing SSL connection.

E-PKI Manager/OU=InstantSSL/CN=secure.ibackup.com Error 20:unable to get local issuer certificate Disconnecting from site secure3.ibackup.com So, I have a certificate problem. I looked through the MacPorts GMANE archive and couldn't find anything related to gFTP. This may be more of an SSL question, but I don't have a clue where to start. a. Do I need to install another application using MacPorts, such as openssl? b. How do I get and install certificates? Thank you. Peter
